Curious if anyone keeps and re-purposes old motor oils? I'm aware that these might have a acidic content so the may not be ideal as lubricants. But then again, they may have some purposes, especially relatively lightly used motor oils changed only on 6 or 1 year intervals if you have a vehicle you maintain but rarely drive.
I'm thinking it's useful as parts soak tank, for old hinges and whatnot. Also good to help get fires started, especially damp wood such as camping or cookouts, or back yard fire pit, etc.
I've read that folks use old motor oil to coat ground contact or bottoms of fence posts to prevent rot or bugs, or used as an alternative to stain wood.
What's the consensus?
